HARVEY .B. LINDSAY, OF OAKLAND, CALIFORNIA, ASSIGNOR TO THE DRY-ZERO COR- PORATION, OF OAKLAND, CALIFORNIA, A CORPORATION OF CALIFORNIA.

REFRIGERATOR AND ICE MACHINE.

Application filed January 25, 1922.

To all whom it "may concern:

Be it known that I, HAnvnY B. LINDSAY, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new'and useful Improvements in Refrigerators and Ice Machines, of which the following is a specification;

My invention is an improved overhead refrigerator and ice machine in which ice is frozen in small cubes to be placed in drinking glasses to make icewater.

My invention is an embodiment of and improvement on my refrigerator disclosed in my co-pending application filed August 9, 1921, Serial Number 490,904 now Patent Number 1,437,529, Dec. 5, 1922.

Referring to the; annexed drawing in which my invention is illustrated and which forms a part of this specification:

Figure 1 is a longitudinal vertical section of my invention.

Figure 2 is a perspective view of the ice mold drawer.

Figure 3 is a view showing the drawer opening through the side wall of the refri erator.

n the drawing 1 indicates the body of my refrigerator and 2 a turret upstanding from the upper wall of said body. A receptacle 3 is formed with a body 4 and with extensions 5 and 6 at the bottom and the respective sides of said body, said body fitting the turret 2 and said extensions extending under the upper wall of the refrigerator body 1 at the sides of said turret respectively. The upper walls of the extensions 5 and 6 incline upwardly to the receptacle body 4. The body 4 of the lcceptacle 3 has a hopper 7 in the top thereof which extends above the turret, through which hopper brine 8 and ice 9 are placed in the receptacle. The refrigerator body has a door 10 through which articles are placed in the body below the receptacle 3 or taken out of the receptacle.

Serial No. 531,556.

. water before the drawers l3 and 14 are introduced in the chambers 11 and 12.

The colder brine being at the bottom of the receptacle 3 will have its temperature raised above that of the body of the brine by the heat of the articles in the refrigerator. This warn'ied brine will now rise ,to the top of the receptacle 3 and upwardly along the inclined walls of'the extensions to the ice compartment. being replaced by the colder upper strata of brine. This circulation is continued to lower the temperature of the refrigerator and freezes the water in the molds 15 into ice cubes which are placed in drinking glasses.

The molds may also be formed in different shapes, to conform to different requirements.

Having described my invention. I claim:

A refrigerator and ice machine comprising a refrigerator body adapted to receive articles of food, a receptacle in the upper part of said body in which is placed brine and ice, a chamber extending through said receptacle and about which the brine circulates and a drawer constructed with a plurality of transverse and longitudinal walls, which drawer when filled with water is introduced in said chamber from the outside of the refrigerator. said drawer having a flange on its outer face adapted to engage the outer surface of the refrigerator. said flange serving as a stop for thc dran'cr and also as an insulating means.

In testimony whereof I 'atlix my signature HARYE Y B. LIX USA 1'.
